Here is a copy of our config http://pastebin.com/bTksv06L

In game, for some reason no bloodwood trees are spawning, if you place saplings down and bonemeal them (even in creative) they never grow, and there are no bloodwood logs in the NEI/JEI. There are however bloodwood planks listed.

If we follow the format of log0 = plank0, then we have nether_log:0 and nether_plank:0, but then we encounter nether_log:1 and nether_plank:2, nether_log:2 and nether_plank:3. This leaves nether_plank:1 (bloodwood planks) with no logs to craft them from.

This looks to be an item mismatch, in which the Darkwood which should be nether_log:2 and the Fusewood which should be nether_log: 3 are being assigned the wrong item meta ID value.

Also this appears to be the only log that is missing/being affected. all of the overworld logs and planks are fine, as are the rest of the nether logs and planks. Only Bloodwood seems to be missing/affected.
